Long-chain fatty acids are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Thus, 9,10-dihydroxystearic acid is considered to be an octadecanoid lipid molecule. 9,10-dihydroxystearic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). 9,10-dihydroxystearic acid can be found in peanut, which makes 9,10-dihydroxystearic acid a potential biomarker for the consumption of this food product.
